Thawj tiam ntawm excavators: qhov tshwm sim ntawm hluav taws xob motors thiab combustion engines muab excavators siab heev thiab haum cov khoom siv hluav taws xob, ua rau yug ntawm ntau yam excavator khoom. Xyoo 1899, thawj lub tshuab hluav taws xob excavator tau tshwm sim. Tom qab Tsov Rog Thoob Ntiaj Teb thib 1, lub tshuab hluav taws xob kuj tau siv rau hauv excavators, thiab hom tshuab excavator siv los ntawm diesel xyaw (los yog hluav taws xob motors) yog thawj tiam ntawm excavators.
Thib ob tiam excavators: Nrog rau kev siv dav siv tshuab hydraulic, excavators muaj ntau yam kev siv tshuab kis tau tus mob, thiab hloov cov khoom siv sib txuas nrog hydraulic kis tau tus mob yog qhov loj tshaj hauv kev siv tshuab excavator. Nyob rau hauv 1950, lub teb chaws Yelemees thawj hydraulic excavator tau yug los. Hydraulic mechanical kis tau tus mob yog qhov thib ob tiam excavator.
Peb tiam excavators: Kev siv dav siv hauv tshuab hluav taws xob, tshwj xeeb tshaj yog siv tshuab computer, tau ua kom cov excavators muaj kev tswj hwm lub tshuab, thiab tseem tau coj mus rau kev tsim cov excavators rau kev ua haujlwm siab, automation, thiab kev txawj ntse. Qhov tshwm sim ntawm kev sib koom ua ke ntawm mechatronics tau tshwm sim nyob ib puag ncig xyoo 1965, thaum kev siv tshuab mechatronics ntawm cov khoom tsim tawm hydraulic yog nyob ib ncig ntawm 1985, feem ntau yog tsom rau kev txuag hluav taws xob. Lub tshuab hluav taws xob ntawm excavators yog lub cim ntawm peb tiam excavators.
Cov tuam txhab kev lag luam excavator tuaj yeem muab faib ua plaub pawg. Ntau tshaj 70% ntawm domestic excavators yog nyob rau hauv txawv teb chaws hom, thiab domestic hom tseem tsuas yog me me thiab nruab nrab excavators. Txawm li cas los xij, qhov sib faib ntawm cov excavators hauv tsev tau maj mam nce, nrog rau ib xyoos ib zaug nce ntawm 3.6% hauv 2012.
